I'm running the Windows and Mac version. I still consult for the high school I went to and worked at for a long time and just helped them upgrade 200 computers to OpenOffice. We figured it will save them $25,000 every 3 years or so. The only linux machines I have are CentOS (a version of Red Hat) and we use those as our web servers for our software. They don't actually have a GUI so we only use vi (super geeky text editor). Al, actually Microsoft is the ANTI standard. Their file types are closed so only people with MS Office can open them. There's a world wide consortium that voted Open Office's format the open standard. Microsoft had proposed a version but got caught bribing at least one country so they ruined their chance. The most interesting thing is that several states such as Massachusetts have converted ALL government offices, including schools to Open Office. Many other states such as California, Nevada and Texas have legislation about the issue being discussed now. It doesn't make sense to have government files as doc's if you need to spend a few hundred bucks to open them. Any software program can add code to open Open Office's files, not true with MS.
